What a crew! Kim Kardashian was one of many celebrities to attend Jimmy Fallon's Tonight Show debut Monday night in NYC. And in a moment that will probably never come again, the Keeping Up With the Kardashians reality star took part in a star-studded photo-op alongside Joan Rivers, Lindsay Lohan, Lady Gaga, and many other celebs from TV, music, movies and more.

"Mike Tyson, Sarah Jessica Parker, Tracy Morgan, Joan Rivers, Gaga, Lindsay Lohan backstage at Jimmy Fallon tonight!" Kardashian, 33, wrote via Instagram on Feb. 17. In the incredible photo, Kanye West's fiancee is standing next to Lohan and the E! Fashion Police host (Who has, needless to say, thrown a jab or two at all of the ladies in her day.)

Kardashian's surprise appearance also brought about a run-in with Seth Rogen, her "Bound 2" satirist. "You guys watching Jimmy Fallon tonight? Fun behind the scenes pic with these funny guys, Seth Rogan & Tracy Morgan," Kardashian wrote, with a pic of the trio.

Last November, Rogen, 31, and his pal James Franco, 35, spoofed Kardashian and her fiance after the couple released a video of the rapper's song "Bound 2." As did Kardashian, Rogen went shirtless as he straddled Franco on a motorcycle. The This Is the End costars even went in for an intimate kiss!

Luckily, North West's parents thought the "Bound 3" video was hilarious. "You nailed it!!! Sooo funny!" Kardashian tweeted at the time. "Kanye says what's up! He loves u guys! He laughed so hard at this."

"Thanks!" Rogen, 31, replied back. "Some of those positions were really uncomfortable. That s--t is harder than it looks."
